Scope of Contract EPC

Segment

Oil & Gas

The pipeline construction is divided into two sections: the first is approximately 110 kilometers long, from Allen to Chelforó, and the second is 327 kilometers long, from Chelforó to Punta Colorada.

The magnitude of the project and the challenging deadlines require the use of advanced technologies such as automatic welding and double-joint plants. The construction of 22 special crossings is another technical challenge that must be overcome. The crossing over the Río Negro will be carried out using horizontal directional drilling (HDD) technology.
